Application filed March v15, 1927, Serial No. 175,622, and in Great Britain December 20,1926.

The's'ealing of the lids of boxes, bottles andthe like by means of adhesive tape has hitherto been done by hand, and has been comparatively slow. f i 3 The present invention has for its object to provide mechanical' means for applying the tape.

According to the invention, a machine is provided in` whichl the end of the tape, drawn from a reel, is laid betw-een the box or other receptacle and a yielding or floating'roller, and by moving the roller bodily around thereceptacle, the tape is wrapped around the receptacle at the junction of the lid andthe body of the receptacle, the machine being automatically stopped and the surplus tape being cut off after a complete band of tapehas been rubbed or rolled down on to the receptacle.

r Upon the accompanying drawing Fig. 1 yillustrates a face view, partlyV ybroken away, and

Fig. 2a plan view, partly in section of a machine constructedaccording to the invention. v v p Fig. 34 illustrates a vertical cross sectional elevation of the machine.

The improved vmachine comprises a pedestal bearing a secured by bolts and nuts b i to la bench or table c. Mounted in the bearing a is one endof a hollow shaft d, the Vshaft being held stationary vby a set screw e. rRotatably mounted on the Shaft is a three-armed member 7", on the 'hub f1 of 35 which is rotatably mounted a belt pulley g. Between the member f andthe pulley g is a; fibre or Alike friction disch. Between the pulley and a ring held on the hub f1 by a screwed collar f2, is aspring y' for normally 40 pressing'the pulley against the disc 7L and )the disc 7L against the member f, a pin 7c on the ring c' (slidably fitting a hole in the pulley hub) servingl to prevent relative rotary movement of the pulley and ring. In the shaft d is a longitudinal groove Z1 suppliedwith oil through an oil cup Z2 yfor lubricating the parts. At the front end of the shaft d is a Collard3 for retaining'the member f on the shaft.

Extending through the shaft d is a rod Z 'to one end of-.which is connected a disc m with recessed face on the side furthest from concentric therewith by the small hub part Vboss is a pin a3.

nut ln..

To one arm of the member f is applied a flanged pulley, the stud axle 0l of whichis fixed by a Set screw p to the arm. While one flange g of the pulley is in one with the stub axle and barrel of the pulley, the other flange 1' is separate and is adjustably connected to the barrel of the pulley by a screw s and nut t. Between the two flanges ofthe of the'disc and 'by the rod Z and the wing v pulley a r-eel of adhesive tape r1 can -be e placed, the flange being slotted to allow of quick removal and replacement, and after replacement serving to put a slight drag ron the reel of tape to prevent over-running.

To another arm of the member f is pivotally connected a lever arm or linkv u, which at its free end is fitted with arubber'- covered roller c. This roll-er lies and r0 tates -in the same, plane as the Areel of adhesive material. It also lies and rotates limmediately over the axial centre line of the shaft 0l. A Screw u1 in the link anda stop u2 on the arm of the member f Serve to regulate the extent to which the roller may approach the axial line of the shaft d, against the pull of a regulatable spring fw acting as between a lug w1 on the reelcarrying arm and a pin 'a3 on the link u.

In one with the pedestal bearing a is a boss a1 and web a2 and passing through said part of said pin is a lever with cranked arm 021 which lies alongside the web a2. In

said web is a hole and through such hole loosely passes a spindle y fitted with a spring y1 and nuts y2, the spindle being connected i at one end to the arm m1 of the lever a. By means of the spring the longer armof the lever is normally held in a horizontal position. On its upper facet-he leveris formed with a shoulder 002 against which the third arm of the member f is adapted to abut, when the lever is horizontal. To the free end of the lever is connect-ed the link rod e1 of a foot pedal z. v The disc m constitutes a c,centre, and is interchangeable with centres of various sizes, Further, the recess in the `face of the disc is shaped to suit the shape of receptacle requiring to be taped. In the example shown the centre is suitable yfor a circular recep tacle.

In proceeding to use the machine, ,the re eeetaele requiring to ,be tapes placed. lid

Secured to a protruding foremost into the recess of the disc m and held in such position by hand. In the drawing a circular box is shown. The free end of the adhesive tape is then brought forward and its adhesive face pressed on to the box at a point where its width will lie across the edge of the lid, the pressure of the finger being sufficient to initially fix the tape to the box and the roll-er e afterwards pressing upon the tape. The foot pedal is then depressed, thereby drawing down the lever no and freeing themember j", whereupon, by means of a power belt applied to the pulley g, the member f is rotated in the direction of the arow, see Fig. l, and the tape caused to wrap around the box, until it has completely encircled the box. At the same time, the rubber-covered roller 'o moves around the box and presses or rolls down the tape into close Contact with the box at all parts of its Width.

After starting the machine the operator removes hisv or her foot from the foottreadl-e a, and the lever w is free to riseup to its normal position, so that when the third arm of the member has completed one revolution, it meets the shoulder m2 of the lever and its motion is automatically arrested. That portion of the tape surrounding the box is then severed from the main length by means of a pair of scissors, or the like and the taped box is removed and a fresh one inserted, the end of the tape applied to the new box, and the machine restarted.

The friction disc L allows of a slip between the pulley g and the member f when the arm of the latter engages the shoulder m2.

By the substitution of discs m of different sizes, and with recesses of different shapes, receptacles of various sizes and shapes can be taped.

To protect the operator, a light metal shield e2 is applied to the machine, such shield being .secured to the three-armed member f by screws, applied at z3, 2*, And to allow for the angular movements of the pressure roller and its axis, a curved slot as is cut in the shield, see Figs. l and` 2.
